Identity in the Late Woodland Northeast: interpreting communities of practice from paste composition at the Thomas/Luckey and the Losey 3 sites

Thomas/Luckey’s 13th -15th and Losey 3’s 14th-17th century occupations in the Late Woodland Northeast contain assemblages with incongruous regional pottery types; Kelso Corded and an assumed non-local Shenks Ferry. I argue the presence of Shenks Ferry vessels at these two sites indicates the movement of people who reproduced their natal designs upon arrival, rather than trade. The question of whether identity and communities of practice can be discerned from pottery decorations and paste was answered by analyzing sherds with pXRF. While pottery types are based on visual attributes, pXRF looks at elemental composition. Decoration is mimicable, but paste is not; paste accurately illustrates a vessel’s origin. Cultural groups are not static entities, and internal development or outgroup interaction indicates change. Communities of practice recreate themselves in a new environment and in relation to others. The results of this analysis add new depth to conceptions of group movement and identity construction

On the optimization of low dosage application systems : Improvement of dose advice and early detection of herbicidal effects

Application of herbicides at rates below the recommended label dose has received considerable attention in recent years as it is a means of reducing overall herbicide use. To minimize the risk of inadequate weed control in these situations, the Minimum Lethal Herbicide Dose (MLHD) technology, which was specifically developed for the use of low rates of photosynthesis inhibiting herbicides, relies on an appropriate calculation of the optimum herbicide dose and on an early detection method of herbicidal effects to evaluate the efficacy of the treatment shortly after application. The study described in this thesis was undertaken to further improve the prediction of the optimum dose of photosynthesis-inhibiting herbicides and to explore the opportunities of expanding the MLHD-technology toacetolactate synthase (ALS) inhibiting herbicides.The first part of the study examined the influence of pre-spraying weather factors on the efficacy of photosynthesis-inhibiting herbicides. The results put forward that pre-spraying weather conditions have a considerable effect on herbicide efficacy and that this effect is mainly through an effect on herbicide uptake. Herbicide-specific correlations between uptake and individual weather parameters were found. These correlations were non-species specific and indicate that inclusion of pre-spraying weather conditions in advisory systems that recommend on the use of reduced herbicide dose rates is recommendable.In the second part of the study theextension of the MLHD technology to acetolactate synthase (ALS) inhibiting herbicides, particularly the development of an early detection method of herbicidal efficacy, was explored.Application of the ALS inhibiting herbicides metsulfuron-methyl on Solanum nigrum and Polygonum persicaria plants resulted in a progressive reduction in CO 2 fixation and the relative quantum efficiency of photosystem I (Φ PSI ) and photosystem II (Φ PSII ) electron transport, emerging a couple of days after herbicide application. Ф PSII turned up to be one of the most promising and practical parameters to use when designing an early detection method for sensing the toxicity of metsulfuron-methyl. The loss of Ф PSII was light-dependent and could be earliest detected at the base of the youngest leaf of treated plants

Successful field pea harvesting

Many thousands of hectares of field peas are harvested trouble free each year. Growers experience together with recent machinery innovations and modifications have solved the majority of harvesting difficulties. Optimum harvesting conditions are in a crop of uniform density on a level soil surface with the machine either working into or across the direction that the crop has been laid by the wind. To make harvest easier the receival standard for moisture in pulses has been lifted to 14 per cent, which allows harvest to begin sooner when the crop is the range of 14 to 15 per cent moisture. Harvesting at higher moisture levels has a wide range of advantages for growers, grain handlers (CBH), buyers and end users of our pulse crops.https://researchlibrary.agric.wa.gov.au/bulletins/1149/thumbnail.jp

Tramline farming systems technical manual

Tramline farming improves farm production and efficiency by controlling traffic and confining compaction to permanent tramlines and reducing overlap. This manual will help you develop your farming system to get the tramline farming benefits. The manual contains information on the principles and techniques of implementing a tramline farming system. There are many options available, so you can tailor the system to suit your own farm. In eastern Australia, controlled traffic farming (CTF) is another term used for permanent wheel track farming. The system is based on bare, straight tramlines. The term tramline farming is more commonly used in Western Australia where the system is closer to the original European concept of using bare tramlines for spraying only to avoid weed and soil erosion problems. Although most tramline farmers work in straight lines, some Australian growers, mostly from Western Australia, have shown that tramline farming can be worked successfully round and round. The terms tramline farming and controlled traffic farming can be used interchangeably. For the purpose of this manual we will refer to tramline farming.https://researchlibrary.agric.wa.gov.au/bulletins/1192/thumbnail.jp

Major Trends Affecting Australia's Agricultural Industries

As this decade draws to a close, the environment in which Australia's rural industries operate continues to change. Internationally, markets in countries such as Indonesia, Korea and Malaysia are now much more uncertain than they were a year or two ago because of the economic problems that face these countries. In Australia, markets are also changing, not because of an economic crisis, but because of consumer concerns about health. Removal of government intervention in agriculture is still underway as the government pursues the level playing field. At the same time, farm returns remain variable and poor relative to those earned in some other parts of the economy. This paper examines these and other developments that are influencing the rural sector

Sind wir nicht alle ein bisschen Dora? Eine Untersuchung der Funktion psychischer Krankheit anhand der Raumkonstruktion in Irena Vrkljans Buch über Dora

We often encounter mental illness in our daily lives. People who are diagnosed with a mental disorder are marked as different and thereby stigmatized and confined to spacial isolation. This thesis analyzes the function of mental illness by examining the protagonist of Irena Vrkljan's Buch über Dora. I argue that in Buch über Dora stigmatization and isolation of otherness becomes visible in how the book's protagonist is excluded from certain spaces. My main question is which role is ascribed to Dora by society. Othering – and therefore excluding – mentally ill persons such as Dora is necessary to establish the order of society. Another important issue are the similarities between Dora and other female characters in the novel.The symptoms of the pressure to succumb to societal norms are shared by the first person narrator, among others. It is my aim to show that and how all woman can easily be pushed into Dora's role. This leads to the central question or my thesis: Are we not all a bit like Dora? To date, Irena Vrkljan's works have been largely neglected by the germanic academic community. Germanistik has not yet found a way to accommodate her bilingual and bicultural oeuvre. The first part of my thesis addresses this issue. The second part develops a constructivist theoretical framework for my analysis of space. First, I draw on the work of Michel Foucault "Of Other Spaces", "Discipline And Punish", and "Madness And Cilvilization", in which he describes space as a construct that reproduces societal norms. Second, Sigmund Freud's "Fragments of an Analysis of a Case of Hysteria" helps to grasp how mental illness is pathologized. While Foucault focuses on the function of norms, Freud analyses the consequences of aberrant behaviour for women. The third part focuses on the fragmentary structure of the novel and continues with an detailed analysis of heterotopias such as the cemetery, Dora's room, the market and the untended park. By identifying with Dora, Buch über Dora questions the norms and shows her otherness as something that we all share. She may be stigmatized as mentally ill but she is by no means fundamentally different to other women

Brain and lung metastasis of Bartholin’s gland adenoid cystic carcinoma: a case report

INTRODUCTION: Adenoid cystic carcinoma of Bartholin’s gland is a very rare disease. CASE PRESENTATION: A 48-year-old premenopausal woman of Caucasian origin was delivered adjuvant pelvic and inguinal radiotherapy after prior complete left Bartholin’s gland tumor excision and inguinal lymph node dissection for adenoid cystic carcinoma of Bartholin’s gland with one metastatic inguinal lymph node. Two years after primary treatment, she presented to the Emergency Room with acute headache, hypoacousia, decrease in visual acuity, and a decrease in right leg muscle strength. A cranial magnetic resonance imaging scan demonstrated three cystic brain lesions with associated perifocal edema. Chest and abdomen computed tomography scans and a magnetic resonance imaging scan of the pelvis did not find any metastatic or residual disease elsewhere. A physical examination found no local recurrence. Stereotactic brain biopsies with pathology examination revealed the presence of adenoid cystic carcinoma metastasis. She thus received 30Gy of brain radiotherapy but, three months later, the brain lesions did not decrease in size and left mid lobular lung lesions appeared on her chest computed tomography scan. A mid left lobe lung excision was undertaken followed by chemotherapy consisting of six cycles of cyclophosphamide, adriamycin and cisplatin. Five months after beginning chemotherapy, the brain disease progressed and our patient died. CONCLUSION: Our case report shows the difficulty in managing brain and lung metastasis of Bartholin’s gland adenoid cystic carcinoma as no consensus on the optimal treatment exists

Feral goats in south-western Queensland: a permanent component of the grazing lands

Feral goats were harvested in south-western Queensland at four sites under two regimes (opportunistic harvesting and sustained control). We assessed how this impacted on their contribution to total grazing pressure, on soil and pasture conditions and on the economics of goat management. The population impact was not consistent across sites with the same treatment, with 62% and 84% reductions in numbers in the two northern sites (one opportunistic harvesting site and one sustained control site) while numbers in the southern sites essentially remained the same. The contribution of goats to grazing pressure ranged from 3 to 30%; kangaroos contributed 16–36%; and livestock contributed 37–72%. Harvest rates of feral goats calculated for each of the sites ranged from 17 to 41%. There was no consistent relationship between population changes and the harvest rates. Seasonal conditions had greater influence on pasture and soil conditions than did changes in feral goat populations. The average cost of mustering goats (based on 34 operations) was $1.93 per head. Mustering costs increased markedly when goat density was lower than 10/km2. Average trapping costs (based on 7 trapping programs) were$2.08 per head. This compared with on-farm prices of $16–$25 per head in 1997. Personal circumstances and preferences of individual landholders were the key determinant of the level of control undertaken. Variability in price contributed to landholders being apprehensive about the viability of the goat industry. There are few simple tools available for landholders to estimate feral goat numbers and this makes effective management of total grazing pressure difficult
